4.15.18 Action GR (Add/Remove Grid)
Action GR is used in both the screen and report design facilities
Action code GR is used to generate or remove a "grid" from the screen or report image. The grid consists of 2 axes. The horizontal axis indicates the column positions across the screen/report and the vertical axis indicates the line numbers down the screen/report. When action code GR is used the following events occur:
1. If there is already a grid on the screen/report image it is removed.
2. If there is no grid currently on the screen/report image a grid is generated. The horizontal and vertical axes are placed on the screen/report image so that they "cross" at the position the screen cursor was located when the request was made.
